Alfonso Flores-Lagunes, "Finite Sample Evidence of IV Estimators Under Weak Instruments", Journal of Applied Econometrics, Vol. 22, No. 3, 2007, pp. 677-694. The file AppNoPub-1005.pdf contains the additional simulation results referred to in the paper. This PDF file should be readable using Acrobat Reader or any other program for reading PDF files. In addition, this file contains explanations of the three different data sets used in the paper to illustrate the different IV methodologies. All datasets have been analyzed before. 1. Data on 329,509 men born in the 1930s taken from the US census and originally analyzed in Angrist and Krueger (1991), "Does Compulsory School Attendance Affect Schooling and Earnings?", Quarterly Journal of Economics, 106: 979-1014. The same data were also analyzed by Angrist, Imbens and Krueger (1999), "Jackknife Instrumental Variables Estimation", Journal of Applied Econometrics, 14: 57-67; and therefore the data are available through the JAE Data Archive at http://www.econ.queensu.ca/jae/1999-v14.1/angrist-imbens-krueger/ 2. Quarterly Data from 1947.3 to 1998.4 for the US analyzed in Yogo (2004), "Estimating the Elasticity of Intertemporal Substitution When Instruments are Weak", Review of Economics and Statistics 86: 797-810. The data are available at http://finance.wharton.upenn.edu/~yogo/data/EIS_Data.zip 3. Data on 602 Swedish males used in Blomquist and Dahlberg (1999), "Small Sample Properties of LIML and Jackknife IV Estimators: Experiments with Weak Instruments", Journal of Applied Econometrics, 14: 69-88.
